(AP)—Chevron CEO John Watson notices something important as he visits his company's operations around the globe: Governments everywhere find high energy prices much scarier than the threat of global warming.

(Phys.org)—For some Americans, it is our energy dreams come true. To others, it is an environmental nightmare. Ever since a new drilling technology, called hydraulic fracturing or fracking, made it possible ...

In the Colorado mountains, a spike in air pollution has been linked to a boom in oil and gas drilling. On the plains of north Texas, there's a drilling boom, too, but some air pollution levels have declined. ...

Developers of renewable energy and shale gas must overcome fundamental geological and environmental challenges if these promising energy sources are to reach their full potential, according to a trio of leading geoscientists. ...

University of Michigan researchers are conducting a detailed study of the potential environmental and societal effects of hydraulic fracturing, the controversial natural gas drilling process known as fracking.

In communities across the U.S., people are hearing more and more about a controversial oil and gas extraction technique called hydraulic fracturing – aka, hydro-fracking. Controversies pivot on some basic questions: Can ...

(Phys.org)— Initial results of clay samples from western North Dakota show varying percentages of alumina content, a finding of interest to the North Dakota Geological Survey that commissioned the study. ...

Stony Brook University scientists have found that the disposal of contaminated wastewater from hydraulic fracturing  commonly known as fracking  wells producing natural gas in the Marcellus Shale region ...
